Multiple Antenna-Aided Spectrum Sensing Using Energy Detectors for Cognitive Radio
نویسندگان
چکیده
Recently a spectral scarcity has arisen as a serious problem, because current static frequency allocation schemes cannot further accommodate an increasing number of devices requesting higher data rate. Therefore, CR (cognitive radio) technique has been considered as a potential solution to improve spectrum utilization by sharing the spectrum. In this chapter, the main concept of CR was introduced.
